This edition’s cover features Alexandra Kosteniuk. She is the 12th

woman to hold the

title of World Women’s Chess Champion. What a tremendous accomplishment! I

was honored that she allowed me to use her photo for the cover, allowed me to

interview her for UON, sent another photo, and two high level chess games which

she took time to annotate. The interview starts on page 1. I hope you will read her

interview, play over the games, and visit her chess links.

Davide Rozzoni, Tim Sanders, and Daniel Todd put forth a colossal effort in creating a

large section on du Chattel and his Nh6 games. Clive Hill has written a nice article on the Scandinavian Center

Counter, and David Kane has provided us with some interesting material on the Tayler. David made his own pdf in

a neat two-column format, a great help to me. I appreciate all contributions.

As for the great tardiness of this issue, it is my fault. It has a lot to do with a factory shutdown and my unexpected

relocation to Austin, Texas… 1500 miles from my home near the shores of Lake Erie; but more importantly, 1500

miles away from family and friends.

An Interview with Alexandra Kosteniuk

12th Women’s World Chess Champion

by UON Editor G. K. Gifford

Alexandra Kosteniuk likely needs no introduction, but, just in case you do not know, let me tell you that she is the 12th Women’s World Chess Champion, as well as a model. In December of 2009 I had conversed with Alexandra a few times via e-mail. We discussed a few topics, e.g., the cover for this issue of UON, chess instruction, and the possibility of an interview. And thus, here is the interview. Gary: Alexandra, I want to first

congratulate you on becoming the 12th

Women's World Chess Champion."

That is an extremely impressive

accomplishment. I also want to thank

you for providing UON with a very nice

cover photo and the photo of you and

Ms. Judit Polgar, and of course, the

games and analysis of yours that will

follow.

Alexandra: Thank you, Gary, it is a

pleasure for me to be featured in UON

and to be able to talk to your readers :-)

Gary: How old were you when you became aware of chess, who taught you, and how did you

get so good at it?

UON 26


Alexandra: My Dad taught me chess when I was 5 years old. I think there were several factors

that helped me become very good. First my Dad was very convincing and I was very well

behaved, I wanted to make him happy, and he was especially happy when I solved his chess

problems and puzzles. Also, he had a great system to teach good chess visualization of the

board, and already when I was 5 or 6 he gave me exercises to imagine the board in my mind, for

example I had to close my eyes and say what color the square "e5" was. Then more and more

blindfold exercises such as "How can a knight get from a1 to g8, on which squares", etc. The

more you train like this, going from easy to more complicated, the better you'll be able to

calculate chess variations.

Gary: Who are your favorite chess performers from earlier chess times? Who, if any of these,

do you try to emulate in your style of play?

Alexandra: I love all world chess champions, they have all created wonderful masterpieces. And

those styles are so different, that it's almost not possible to compare them and to say who is better

than another, they are all great! I have my own style, and don't try to copy anybody.

Gary: What are your favorite openings for White?

Alexandra: I always play 1.e4 and am ready for anything. I especially love the Ruy Lopez, with

all the strategy than can ensue and small maneuvering that can lead to fearless unexpected King-

side attacks.

Gary: What are your favorite defenses for Black?

Alexandra: In the last years I have widened my opening repertoire, so that my opponents would

not know what I play. For example against 1. e4 I will gladly play the Ruy Lopez, but also the

Petroff, and of course the Sicilian. I have even played the Scandinavian to surprise my

opponents.

Gary: What general advice would you give to chess players (expert and lower) in regard to

improving their play?

Alexandra: First if they love chess they should try to train in a serious manner, that means

analyze their games post-mortem very well. Never play more than 10 blitz games in a row before

entering them in a computer chess database system and finding improvements. Never play a

game without recording its moves. And of course it's great to study a book on chess endgames

and do a lot of middle game tactic puzzles.

UON 26


Gary: Of all the chess games you have ever played, do you have a favorite? Perhaps the final

game of your World Championship play-offs? Or perhaps one of the rapid chess games where

you took down a high level GM or IM?

Alexandra: I have many favorite games, actually I have just published my new book "Diary of a

Chess Queen", in which I comment in great detail my 64 favorite chess games, from when I was

10 years old (in 1994) until I became World Champion by beating the Chinese Hou Yifan. I also

have very nice blitz wins very recently against Magnus Carlsen, Vishy Anand, Levon Aronian

and several others, but blitz of course is not as important as classical games where I won

important titles in my career.

Gary: In addition to chess, some UON readers may not realize that you are also a fantastic

model capable of many different looks... (with all the photos I've seen being very impressive).

How did you get involved in modeling? Do your modeling and chess careers ever conflict with

each other?

Alexandra: Actually it's FIDE who, in 2001, asked me to be "the face" of chess, and I did my

first photo shoot for a chess uniform. After that I was lucky to be invited by famous fashion

photographers and magazines, but usually all the time it was to accompany articles about me and

about the game of chess, so I think in that way I have done a lot so that people in the non-chess

world have heard of chess.

Gary: Before concluding this interview, I would like to let the readers know that I have a copy

of your DVD, "Kosteniuk World Chess Champion, How I became the Women's World Chess

Champion by Chess Queen Alexandra Kosteniuk." I like the DVD very much and actually

got to employ some of your game analysis ideas successfully in a few of my own games. Is there

anything you would like to say about your DVDs and your chess book?

Alexandra: I have been very active recently, both on the web and in creating products. On the

web, apart from my home pagewww.kosteniuk.com . I started a very successful chess blog for

women, which is called www.chessblog.com , also I have created many free chess videos and

video podcasts on YouTube www.youtube.com/chessqueen and on

www.youtube.com/chesskillertips . I also love to interract with chess players across the world,

for example on Twitter (my nick is @chessqueen www.twitter.com/chessqueen ) and on

Facebook (my page is also called "chessqueen"www.facebook.com/chessqueen) so if anybody

want to send me a message, ask a question, tell me what they think, it's very easy to do so

nowadays and I enjoy it a lot. As for products I am so happy my new book "Diary of a Chess

Queen" came out, it's the story of my life until my world title, and in it I wrote parts from my

childhood diary, it's very personal and gives insight about what it is to grow in chess. The Chess

DVD's also allow you to see my games commented in an easier format, and if you watch them 2-

3 times I guarantee your understanding of chess will increase! All my products are on sale

on www.chessqueen.com .

Gary: Alexandra, thank you very much for taking the time for this interview. I wish you much

continued success for 2010 and beyond.

Alexandra: Thank you Gary, I wish you and your readers also the very best for 2010! May Love,

Happiness and Chess be part of your life in 2010!

{In the first game of our mini-blitz-match with Judit I lost in an even knight endgame, and in the second

game our game once again reached a knight endgame. In the morning of the second day, since my

database crashed and I wasn't able to prepare any openings I spent my preparation hours for reading

the recent chess review magazine "64" in which there was an article by Mikhail Kobalia about the recent

women's world chess championship that took place in September in China. In this article Mikhail talks

about a pawn endgame that arose in the game between Maria Muzychuk and Ju Wenjun. The position

from that game after the 51th move of Black g5 curiously enough resembles the idea that helped me to

win in the game against Judit Polgar.}

by D. Rozzoni together with Tim Sanders and Daniel Todd

This is the concluding article on du Chattel’s ¤h6 games. It contains 164 tournament & team games. As you can imagine, when one chooses to publish all the games of a single player, you find good and bad games. Every chess player plays great games and poor ones. du Chattel is no exception. You will find games where IMs are beaten implacably by the ¤h6 hero and sometimes bad days when black loses rather quickly. I am grateful to Tim Sanders and Daniel Todd as they have annotated five games each. Their work can be found in this article. In the beginning I thought I could offer annotations on every game. Although soon I realized it would have required too much time. So after the games played in Aug. 1987, you will find a few annotated games. The most of the annotations follows the games chosen by IM Welling for his Kaissiber’s article (see more at the end of this work). Once again I want to express my appreciation to Philip du Chattel for the great fun I have while I play through his exciting ¤h6 games. At last, this article is dedicated to all du Chattel’s fans. A little bird told me that when du Chattel was an active chess player there were quite a few of them! Nieuwenhuis,Pieter - du Chattel [B00] 16.01.1986

The following five games have been annotated by Tim Sanders. These games were

analyzed with the assistance of Rybka 2.2

Here, du Chattel takes on Nicolaas Hauwert, not really a UCO-type player. He topped

2300 in his 20 year career.

The following five games have been annotated by Daniel Todd .

Te Winkel,H - du Chattel,P [A40] 12.03.1987 [Daniel Todd]

1.d4 g6 [1...Nh6 can prove problematic to Black after 2.Bxh6 (2.e4 Fritz rates this as

slightly better than 2.Bxh6, but I think they're about equal. 2...g6 (2...d5 is what Fritz

suggests, but I think it's a better idea to avoid the doubled h pawns.) 3.Nc3 There are

several other moves that are playable also. 3.c4, 3.Nf3, 3.f4 are some that come to mind.

In my experience I've had more success with erecting a more subdued pawn center with

e4, d4, Nf3, and Nc3. It's more a matter of taste though. 3...f6 This is perhaps more in

keeping with du Chattel's original concept of Nh6, but other moves may be more

advantageous to Black. a)3...Bg7 4.Nf3 c6 5.Bf4 d6 (a)5...f6 creates a flight square on f7

for the knight in the face of Qd2 or Qc1. 6.Qd2 Nf7 7.Bc4 0–0 White has developed

logically and is ready to castle, possibly on the queenside initiating a kingside pawn storm.

However, the position is quite even and it's anyone's game really. Amazing how resilient

Black's unusual development is.) 6.Qd2 The knight will now have to find a new home,

most likely on f6 via either g4 or g8. 6...Ng4 7.0–0–0 Nf6 8.Be2 (a)8.Bc4 Trying to get the

bishop to an aggressive diagonal leads to 8...b5 9.Bd3 Otherwise the e pawn falls. 9...b4)

2...gxh6 3.e4 c5 (3...d5 is recommended by Fritz, but I like 3...c5 better, it forces White to

weaken the h8-a1 diagonal and allows the Black queen to get into the game.) 4.dxc5

(4.c3 cxd4 5.cxd4 (5.Qxd4 Rg8) 5...Qb6 highlighting the absence of White's dark squared

bishop.) 4...Qa5+ 5.c3 Qxc5 6.Nf3 Nc6 7.Nbd2 Bg7 8.Nb3 Qb6 9.Bc4 d6 Despite the

damaged pawn structure, Black has managed to get an equal position.] 2.e4 Nh6 3.Nc3

c6 [3...f6 4.f4 In my study of games featuring Nh6, I have found that often White gets

overzealous in their attempts at steamrolling Black. I am not a fan of the aggressive f4 as I

think Black can get good chances countering against the White center. 4...Nf7 5.Nf3 Bg7

[5...d5 Recommended by Fritz, but having seen how well Black does in other lines where

he plays f6 I wouldn't hesitate to play it. 6.0–0 (6.exd5 This leaves the f5 square vulnerable

and the d4 pawn could possibly become weak without backup from the c pawn. 6...cxd5)

1.d4 g6 2.Nf3 Nh6 3.g3 [3.c4 Bg7 4.e4 c5 (4...c6 While I personally prefer 4...c5, I have

no doubt du Chattel would have preferred this continuation 5.Nc3 d6 6.Bd3 0–0) 5.dxc5

Fritz suggests this as White's strongest, I personally would prefer to keep the tension in

the center with 5.Nc3. 5...Qa5+ (5...Na6 An interesting continuation and possible

improvement. With both knights on the edge, Black definitely must have a flair for the

unusual. 6.Nc3 0–0 7.h3 White wants to play Be3 without being threatened with Ng4. 7...f5

(7...Nxc5 8.Be3+- Not so much threatening c5 as the knight on h6 after Qd2.) ) 6.Bd2

playing 8.d5 right away. 8...Nd7 9.d5 Ne5 10.Nxe5 fxe5 Black has many ways to chip

away at White's center.] 8...c5 9.Rb1 Qe8 10.a3 g5 11.b4 Nd7 12.bxc5 Exchanging on c5

only allows Black a nice square for his knight. [12.Qc2 cxb4 (12...Qh5 Continuing with the

Bijvank,B - du Chattel,P [B06] 14.03.1987 [Daniel Todd]

1.e4 Nh6 2.d4 g6 3.f4 White chooses an aggressive continuation, trying to push Black off

the board. The danger of this is that White is playing directly into Black's plans and he may

find that the large center is actually quite vulnerable. 3...c6 Simply preparing d5 and is a

favourite of du Chattel's. [3...d5 This move has been played frequently by Kindler and

would be my choice as it hits White's center right away. 4.Nc3 dxe4 5.Nxe4 Bg7 6.Nf3 Bg4

7.Be3 Nf5 8.Bf2 Bxf3 9.Qxf3 Nxd4 10.Qc3 Nbc6 11.0–0–0 Qd5 12.Nc5 0–0–0 13.Bxd4 Bxd4

Nxf2+ 28.Kg3 Nxh1+ 29.Kf3 g4+ 30.Ke2 g3 0–1 Kamal,T-Kindler,J/Wiesbaden 1994/GER]

4.Nf3 d5 5.Nc3 Bg7 6.Be3 A logical placement for the bishop, but White must be on watch

for moves like Ng4 and Nf5 (after f5 and an excange of pawns) which when timed correctly

can prove devastating. 6...0–0 7.Qd2 White is lining up for attack down the c1–h6 diagonal

and also prepares for queenside castling. 7...Qa5 8.Bd3 [8.f5 Too soon. Black can brush

off this threat easily. 8...dxe4 9.Bxh6 Bxh6 10.Qxh6 exf3 11.fxg6 f2+ 12.Kxf2 fxg6+= Fritz

6] 8...dxe4 9.Bxe4 [9.Nxe4 Qxd2+ 10.Bxd2 White retains some developmental lead and

Black still has to reactivate the out of place knight. But Black's position is without real

weaknesses.] 9...Rd8 10.Bd3 Seems a wasted move to capture with the bishop and then

retreat on the next move. 10.0–0 or 10.0–0–0 depending on your tastes both seem fine.

10...Nf5 The knight takes up a familiar post. 11.0–0 Na6 [11...Nxd4 12.Nxd4 Bxd4 13.Bxd4

Rxd4 is fine, but 11.Na6 gets the other pieces into the game.] 12.Qf2 Nb4 13.Be4 Nd6

14.a3 Nxe4 15.Nxe4 Nd5 16.Bd2 [16.c4 Nxe3 17.Qxe3 Qb6 White has an impressive

19.c4 Nf6 20.Ng5 Qxb2 21.Ngxf7 Rf8 22.Ng5 White has not been able to find a good

Caessens,R - du Chattel,P [A40] 09.04.1987 [Daniel Todd]

1.d4 g6 [1...Nh6 See the game Te Winkel - du Chattel for analysis of this move.] 2.Bf4 A

devilishly deceptive move order. 2...f6 [2...Nh6 3.Qd2 Ng4 4.e4 Bg7 5.Nf3 Nc6 6.h3 Nf6

7.e5 I feel the knight moves too much in this line. This is why du Chattel first makes the

preparatory f6, so the knight will have a safe square in f7.] 3.Qd2 Stopping the Black plan

of Nh6 in it's tracks. 3...Bg7 4.Nf3 d6 5.d5 This move doesn't really deter Black from

playing c5 or e5. Perhaps White felt like it increased his control over the e6 square, but it's

not particularly weak at this point as long as Black keeps his light squared bishop. The

advanced pawn can also be challenged via c6 or even c5/e5. [5.e4 Better I think, White

stakes out territory in the center. 5...e5 I think it's important to get some space to develop

the knight (e7) so Black can castle. 6.dxe5 dxe5 (6...fxe5 is also possible, when the knight

can be developed to f6 now.) 7.Qxd8+ Kxd8 It doesn't really hurt Black to lose castling

ability. Take for instance, some lines in the Old Indian where there is an early trade of

queens which result in the loss of castling rights for Black. 8.Be3 Be6 9.Nbd2 Bh6 (9...Nc6

10.0–0–0 Nge7 11.Nb3+ Kc8 12.Nc5 Bf7 Was my original idea, but Fritz suggests the

9...Bh6 idea as better and I'll have to agree it's a little better.) 10.Bxh6 White probably

doesn't want to end up with doubled e pawns. 10...Nxh6 11.Rd1 (11.0–0–0 Doesn't promise

much either. 11...Ke7 (11...Bxa2 is of course no good. 12.b3 Ng4 13.Nc4+ Ke7 14.Rd2±)

12.Bc4=) 11...Nd7=] 5...c5 [5...f5 Opens the long diagonal for the bishop and delays White

from playing e4, supporting the d5 pawn. 6.Nc3 c6= Fritz 6] 6.e4 Nd7 [6...g5 7.Bg3 g4

8.Nh4 f5 is suggested as an improvement by Fritz, but most players would probably prefer

the more sane 6...a6; 6...a6 This leads to the same position as in the game and seems

fine for Black. 7.Nc3 b5 8.Be2 f5] 7.Nc3 a6 8.Be2 b5 9.a4 White decides to force matters

on the queenside. 9.0–0 is also perfectly acceptable. 9...b4 10.Nd1 Ne5 11.0–0 Bd7

Are you interested in learning more about the ¤h6 universal opening system?

If the answer to this question is “YES”, you have:

Option A) The ¤h6 book by Gifford – Rozzoni - Wall http://www.lulu.com/product/libro-a-copertina-morbida/winning-with-the-krazy-kat-and-old-hippo/3457590 This is Rick Kennedy’s review of the book. http://www.chessville.com/reviews/WinningwiththeKrazyKatandOldHippo.htm Fun to write it and fun to read!

Option B)

Kaissiber n° 31 www.kaissiber.de contains a 15 page article on du Chattel's chess written by I.M. Gerard Welling. It is in German language, algebraic notation.. Welling’s choice of the games is superb and his annotations are fine. Furthermore, that article contains some rare & old pictures. A writing that does justice to the player.

The Scandinavian/Centre Counter Defence,

‘Patzer Variation’, with 6…Nd7

by Clive Hill

This discussion of the so-called ‘Patzer Variation’ is fairly limited in its scope and ambition, and if you

would like to study it properly, then I recommend two of Andrew Martin’s internet ‘Bits and Pieces’

articles, http://www.jeremysilman.com/chess_bits_pieces/053003_patzer_var.html and

http://www.jeremysilman.com/chess_bits_pieces/053003_patzer_var_2.html plus his book on the Centre

Counter found at http://www.amazon.co.uk/Essential-Center-Counter-Practical-Guide/dp/1888710225 .

I’m not going to look at all the possible sub-variations of the ‘Patzer’, but simply point out that (whatever

its theoretical merits) the line 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. Nf3 Qc7 6. d4 Bf5 has not

had a very good track record since Andrew recommended it a few years ago. The problem seems to be

that the bishop on f5 becomes a ‘target’ after 7. Ne5 and the line is difficult to play in practice. White has

a big plus score.

As I was preparing this article, I began to wonder about 6...Bg4!?, but instead I’m going to concentrate on

the line I have some experience with; namely 6 ...Nd7!? Unfortunately, at the time of writing some

interesting correspondence games that I am playing with this move are still going on, so I can’t give you

those scores, but I do have some general remarks and advice to offer. Here is my ‘tabiya’ position, after

the moves 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. Nf3 Qc7 6. d4 Nd7!?

UON 26


My experience of this line is that Black does not achieve full equality with best play, but given that very

few White players play 4. Nge2, and that 4. Qe2 is the drawish choice of unambitious opponents; it may

be a useful weapon in two scenarios. Firstly, it may be worth a try against the kind of arrogant, bookish

opponent who will try to blast you off the board with an unsound sacrifice for the ‘disrespect’ of playing

an unorthodox opening. Secondly, if you like the 4...Nd7 variation of the Caro-Kann, and you want to

avoid the Advance, Exchange and Panov variations, you can reach the type of position you favour in

offhand, blitz and practice games relatively easily. Moreover, if further analysis was to find a true route to

equality in this variation, then this line would be a way of avoiding all the ‘heavy theory’ associated with

Nimzovich’s 1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nd7.

I don’t have access to a strong calculating engine, so if anyone can provide computer-generated

suggestions in this line, I would be pleased to hear from them. Also, database games that I am unaware of

would be very helpful. Does anyone else play this variation? The key battleground is the square e5 and

the problem piece is the bishop on c8. Always bear this in mind if you take up this opening! For example,

if White tries to head directly for a slightly odd Caro-Kann with 7. Ne4 then I recommend 7…Ngf6 8.

Nxf6+ gxf6!? 9. 0-0 e6 reaching a position that would normally arise from an unorthodox line in the

French Defence (1.e4 e6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Nxf6+ gxf6!?); Black should have time to

deploy his bishop on b7 after a subsequent …b6.

Analysis

Let us return to the ‘tabiya’ position. White has a tempo to play with because Black has taken 3 moves to

get his queen to c7, but made one less pawn move than in a Caro-Kann. The obvious plan is to attack f7

and

Line A. runs 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. Nf3 Qc7 6. d4 Nd7 7. Bc4 e6!? 8. a4 (!)

Ngf6 9. Qe2 Bd6?! 10. 0-0 Nf8!? 11. Bg5 Ng6 12. d5! Which seems to be just too good for White

(probably ±±). However, the strong Bulgarian Candidate Master Nik Kostov has suggested that the

variation 7 … e6!? 8. Qe2 Be7 9 0-0 Ngf6 is only slightly better for White, so perhaps the Be7 plan can

be used against 8. a4 as well. Play might possibly proceed 8 … Be7 9. g3 Nb6 10. Bf4 Qd8 11. Bb3 Nf6

with Black looking at … c5 and …Nbd5 as partial compensation for losing the battle for e5!

UON 26


Nevertheless, in my opinion, the key move against the Bc4 plan must be 7 ... b5!?. While 8. Bxf7+ is

challenging, Black seems to be able to resist. Hence, 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. d4

Qc7 6. Nf3 Nd7 7. Bc4 b5 8. Bxf7+ Kxf7 9. Ng5+ Ke8 10. Qf3 Ndf6 11. Nxb5 Qa5+ 12. Nc3 is probably

very advantageous to Black, while the more prosaic 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. d4

Qc7 6. Nf3 Nd7 7. Bc4 b5 8. Bb3 b4 9. Ne2 e6 10. Bf4 Bd6 11. Bxd6 Qxd6 12. O-O Ba6 is pretty close

to =.

Can White improve!? Time will tell.

The other significant idea is to redeploy the White Bishop to d3 and most of the rest of this article will

look at this plan.

Line B. My favoured continuation runs as follows 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. Nf3

Qc7 6. d4 Nd7!? 7. 0-0 Ngf6 8. Re1 e6 9. Bd3 Bd6 (9… Be7!?) 10. Qe2 Nd5 leading to a natural ‘fork in

the road’!

Line C: 11. Ne5!? Nxc3 12. bxc3 Nxe5 13. dxe5 Bf8!? is playable, but still ± to White, as if 13…Bc5 14.

Qg4 f5? 15. exf6 gxf6 16. Qh5+! wins a piece.

Line D: 11.Ne4!?

This is a major test of my setup, and it seems to me that Black has four main options to make sense of his

last move (10…Nd5). Castling short, … b5 and …b6 are all legal, but could have been played on the

move before, so for now I’m more concerned with the following possibilities!

Line D1: 11 … Nf4 (!) 12. Nxd6+ Qxd6 13. Bxf4 Qxf4 14. g3 (14. Rad1!?) Qf6 15. Qe4 Qe7 or 15 …g6

(which restricts White’s plus, but certainly isn’t brilliant). Maybe 15 …g6 16. c4 c5 17. d5 0-0 18. Rb1

exd5 19. cxd5 c4!? finally gives Black some counterplay, but = is probably too optimistic an assessment.

Line D2: 11 … c5!? 12. c4 Nb4 13. Nxd6+ Qxd6 14. Be3 Nxd3 15. Qxd3 Nf6 16. Rad1 ±

Line D3: 11. … Nb4 12. Nxd6+ Qxd6 13. Be4 Nf6 14. c3 Nxe4 15. Qxe4 Nd5 16. Qg4 g6 17. Bh6 ±

UON 26


Line D4: 11… Bf4 (?!) 12. c4 Bxc1 13. cxd5 Bf4 14. dxe6 fxe6 15. Neg5 Nf8 16. Bc4 Bxg5 17. Nxg5

Qe7 18. Qe3±

LINE E: Another plan is 7 …e6 8. Re1 Be7 9. Bd3 Nf8!? 10. Ne5 Ng6!?, when 11.Qf3 Nf6 and 11. f4

Qb6 are perhaps just about = (although White still has the initiative). Black is trying to ‘play round’ the

knight on e5 and hit back at a later date. In the f4 line, the extremely unlikely 12. Kh1 Nh6 13. a3 Qxd4

14.Bxg6 Qxd1 15. Bxf7+ Nxf7 16. Nxd1 Nxe5 17 fxe5 b6 18. Ne3 Ba6 even allows me to claim !!

Line F: Chess analysis often proceeds dialectically, and having originally rejected the plans which include

…b5, I decided that if White takes a slightly different approach to my line E, namely 7 … e6 8. Re1 Be7

9. g3!? Ngf6 10. Bd3 Bd6!? 11. Qe2 Nd5 12. Ne4 we have an earlier position from Line D, but with the

extra move g3, which prevents the useful relieving manoeuvre … Nf4. But g3 also means that White has

a slight weakness on the h1 to a8 diagonal, which Black might be able to exploit in the long term.

Unfortunately, 12 … b5 13. a4 b4 14. c4 bxc3 15. bxc3 c5 16. c4 N5f6 17. Nxd6+ Qxd6 18. Bf4 still

looks rather uninspiring! (±; and perhaps even ± ±)

The Future

Clearly there is much work still to be done. One long and interesting variation is 1. e4 d5 2. exd5 Qxd5 3.

Nc3 Qe5+ 4. Be2 c6 5. Nf3 Qc7 6. d4 Nd7!? 7. 0-0 Ngf6 8. Re1 e6 9. Bd3 Bd6 10. Qe2 Nd5 11. Ne4 Nf4

12. Nxd6+ Qxd6 13. Bxf4 Qxf4 14. Rad1g6 15. g3 Qf6 16. c4 0-0 17. Be4!? ...

UON 26


when the main alternatives are 17 ... e5!?, 17 ... Re8 !? and 17 ...Rd8!? These all need to be assessed,

preferably by players more skillful than I.

Further analysis is also required in these lines:

G. 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. Nf3 Qc7 6. d4 Nd7!? 7. 0-0 Ngf6 8. Re1 e6 9. Bd3

Be7!?

I. 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. Nf3 Qc7 6. d4 Nd7!? 7. 0-0 Ngf6 8. Re1 e6 9. Bd3

J. 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qe5+ 4. Be2 c6 5. Nf3 Qc7 6. d4 Nd7!? 7. 0-0 Ngf6 8. Re1 e6 9. Bd3

Bd6 10. Qe2 b5!?

And Finally … A Victory!

One of the advantages/disadvantages of internet correspondence chess is that you can win a game on time

in 12 moves! Pointing the White Queen at g5 was an interesting idea; a shame he didn’t come back for

move 13!

UON 26 BordahBee – A Simple Chess Variant by G. K. Gifford


BordahBee is a two-player board game that I came up with back in April of 2006. I have developed may other chess variants, over fifty, but this one is so down-to-earth that I thought UON readers (or at least some readers) might enjoy the challenge. To play it, you will need an opponent (though 1 person can play against 2, or 2 can play against 2), and you will need two boards and sets of pieces. The name, “BordahBee” is a loose phonetic representation for “Board A, Board B.” It is a chess variant that I created in April of 2006. The game can be played against other opponents on-line at www.chessvariants.com. In addition to the rules of this variant I am including an actual game that I played against a friend and Chess Variants Inventor, Jeremy Good. You can play this game using two standard chess sets. Winning Conditions - You can win by:

Capturing either of your opponent's kings, or,

If your opponent cannot move on both boards during a turn. Note: Moving into check is allowed.

Setup

Two standard chessboards with initial setups. Board A and Board B both have White Pieces at the same compass edge.

Pieces

Standard. Two sets of men required. Two 8x8 boards required.

http://www.chessvariants.com/



Rules

Player 1 sits facing the white pieces on two ordinary chess boards (Board A and Board B), with Board A being to his left. Player 2 sits facing the black pieces. Board A is to his right. Thus Board A is Board A for both players. The significance of “Board A” and “Board B” labels is that there will be two separate games going on simultaneously, and that a player’s move on one board directly impacts his “same-turn move” on the other board. White moves first on either board (A or B). He then moves on the remaining board. But, whatever he moved on the first board has a direct influence on the other, for movement is dictated as follows:

A TURN for a player involves either:

Moving on Board A, then Moving on Board B, or;

Moving on Board B, then Moving on Board A. Moves must be made on both boards. Players can, if desired, alternate which board they move first on for each turn.

To Move a King at the beginning of a turn (on the first board of the Turnat hand) (which can be a move for Board A or Board B) – You must move a Queen or Rook or King on other board after you move your King. To move a Queen at the beginning of a turn – You must follow with a move of King or Rook on the second board. Otherwise your Queen is immobile. To move a Rook at the beginning of a turn – You must follow with movement of King or Queen on the other. Otherwise your Rook is immobile. To move a Knight at the beginning of a turn – You must follow with movement of a Bishop or a Pawn on the other board. To move a Bishop at the beginning of a turn – You must follow with movement of a Knight or a Pawn on the other board. To move a Pawn at the beginning of a turn – You must follow with movement of a Knight or a Bishop on the other board. The rules for pawn en passant apply, as do the rules for promotion. The rules for castling apply. Castling counts as movement of King and Rook… but is a special condition. So, if you castle on your first board of movement… on the second board you could:

castle, or

move the King individually, or

move a Rook individually, or

move a Queen. Win by capturing either one of the opponent’s Kings. There is no stalemate. One player may have no option but to move both Kings at one point in the game, EVEN IF ONE OR BOTH KINGS MUST MOVE INTO CHECK! This is possible and allowed. The other player, upon capturing either King, would then win. You will also win if your opponent cannot move on both boards during a turn.



The following helps simplify the movement concepts Remember: To move the first designated piece on a board, you must follow it with a move of a piece after the “>>” on the other board. K >> Q or R or K Q >> K or R R >> K or Q N >> P or B B >> N or P P >> B or N

If you move this first (on one board):

You must move one of these on the other:

King Queen, Rook, or King

Queen King or Rook

Rook King or Queen

Knight Pawn or Bishop

Bishop Knight or Pawn

Pawn Bishop or Knight

Castle (O-O, or O-O-O) O-O, O-O-O, King, Queen, or Rook

Example of a Possible Game Beginning: White moves 1. Pawn e2-e4 on board B, he must now move a Knight or Bishop on Board A. Bishops can’t move yet (they are blocked by Pawns) so he moves 1. N g1-f3. Blacks move 1. He decides to move on Board A first. He plays 1. … Pawn d7-d6. Now on Board B he must move a Knight on Board B, he plays 1. … N b8-c6. Move 2. White moves his f1 Bishop on Board B to c4. On Board A he must now move a Knight or a Pawn. He plays Pawn a2-a3. Black moves, this time he starts with Board B (but he could start with either board)… 2. … he plays P e7-e6. On Board A he must now move a Knight or Bishop. So, 2…. N g8-f6. And the game continues. Remember, you can move first on whichever board you want. You can switch this on each turn. Board A Board B 1. N g1-f3 P d7-d6 1. P e2-e4 N b8-c6 2. P a2-a3 N g8-f6 2. B f1-c4 P e7-e6 These moves give us the position shown at the beginning of the rules.



Additional Information: Two teams of players (4 people can play). Two people would play at Board A, and two at Board B. The movement rules would remain the same. Opening graphic created with Arena 1.1 and Microsoft Paint. A link to a BordahBee game courier pre-set follows. http://play.chessvariants.org/pbm/play.php?game%3DBordahBee%26settings%3DAlfaerie

A question was asked at the Chessvariants website. Q: If you want to move a unit on one board and you don’t have any armies of the specific caliber required to move on the second board, what happens? Do you simply not move on the second board, or is the first move disallowed? A: Though the sentence doesn't jump out at you, the rules state, 'You will also win if your opponent cannot move on both boards during a turn.' So, the first move would not be allowed in the case you mention. Or, if it were the only move available, that player would lose. A Complete Game The asterisk by a move indicates that the move was made on that board first. Thus on the first move: White played 1.f4 on Board A then 1. Nf3 on Board B. Black responded 1… e6 on Board A and 1… Nf6 on Board B.

Final Position on Board B

The following is how the game moves were entered over the internet. Jeremy Good vs. Gary Gifford

I: Introduction

The Tayler Variation (aka the Tayler Opening) is a line that has been unjustly neglected in my view. The line is of surprisingly recent vintage though it is often confused with the Inverted Hungarian (or Inverted Hanham Defense), a line which shares the same opening moves: 1. e4 e5 2. Nf3 Nc6 3. Be2:

The Inverted Hungarian is an old opening, dating back to the 1860ʼs, at least. Tartakower played it a few times in the 1920ʼs with mixed results, using the continuation, 3...Nf6 4. d3: a rather unenterprising setup for White. In 1981 British player, John Tayler (see biographical note), published an article in the British publication Chess (vol. 46) on a line he had developed stemming from the sharp 4.d4!?. This is a move which apparently no one had thought to play before, and one that transforms the sedate Inverted Hungarian into something else altogether.

Technically, it is really the Tayler Variation to the Inverted Hungarian Defense rather than the Tayler Opening, though through usage, the terms are interchangeable for all practical purposes.

As has been so often the case when it comes to unorthodox lines, I first heard of this opening via Mike Basman when he published a cassette on it back in the early 80ʼs (still available through audiochess.com). The line stirred some interest at the time but gradually seems to have been forgotten. The final nail in the coffin was probably some light analysis published by Eric Schiller in Gambit Chess Openings (and elsewhere) where he dismisses the line primarily due to his loss in the game Schiller-Martinovsky, Chicago 1986. After that, the line seemed to all but die out. However, my own analysis (with the aid of Rybka 3 and Hiarcs 12.1) indicates that this judgment may have been a bit too hasty- more on that later. I have continued to play the line since the mid 80ʼs with very good results- in fact, it has been my main weapon against 1. e4 e5. and I expect it to remain so for some time.

In the box with the aforementioned cassette, Basman included a copy of Taylerʼs article from Chess magazine. Unfortunately, I have misplaced the article, but I did take extensive notes at the time. This present article is based on those notes, some of Basmanʼs analysis from his tape, and my own research and extensive experience with the line. This then will serve as an introduction to those unfamiliar with the line and hopefully revive some interest among those of you familiar with it but perhaps under the impression it has been busted.

II: An Early Deviation

Before we get to the main lines, letʼs examine an instructive early deviation. Looking at the first diagram again, you can see In contrast to the Ruy Lopez or the Italian Game, the bishop on e2 looks rather passively placed and also blocks the e-file

A New Look at the Tayler by David Kane

on a square that potentially compromises the defense of the e-pawn in some lines. But this passive placement has a few positives going for it as well. Psychologically, it may (and frequently does) spur Black to be overly aggressive or to dismiss the system as innocuous. More concretely, the bishop is not a target on e2 as opposed to the more “normal” lines of the aforementioned Ruy Lopez and Italian Game positions where this bishop is frequently a target. This corresponds to Basmanʼs “Non-exposure” theory where he contends that placing certain pieces on passive squares may have compensating factors such as not allowing the enemy to gain tempi from harassing the piece were it on a more exposed square or not allowing a useful piece (such as the White squared bishop) to be exchanged off too early. Also, White has incurred no weaknesses save from the temporarily unprotected e-pawn. But how is White going to engage in any kind of enterprising play? The answer lies below. But first, letʼs look at an early deviation that a lot of lower rated players will play here:

1.e4 e5 2. Nf3 Nc6 3. Be2 Bc5?! this impulsive move allows the hoary fork trick: 4.Nxe5!

Now Black has a choice of 4...Nxe5 5. d4! where White gets a good game regardless of Blackʼs reply, or the slightly better 4...Bxf2 5. Kxf2 Nxe5 where White has a choice of good moves, 6. d4, 6. Rf1 and perhaps the strongest, 6. Re1 which can all be played here with a good game for White.

After 6. Re1 (diagram below), many of my ICC games have continued in tragicomic fashion:

6...Qh4+ 7. Kg1 Qxe4?? 8. d4 Ng6 9. Bf3 1-0

Instead of the suicidal 7...Qxe4 Black can essay 7...d6 with a playable position though White still has the better chances overall. Itʼs interesting to note that this fork trick would not be possible with the bishop on c4 because after 4...Nxe5 the knight would be hitting the bishop on c4. The position of the bishop tucked away on e2 gives the opening certain tactical possibilities not available with the bishop on a more exposed post. The downside is that White may have to lose a tempo to get the bishop off the e-file at some point.

Assuming that Black isnʼt silly enough to fall for any of that, most of your games will feature3...Nf6 which will bring us to the main lines discussed next.

Tayler 2

III: The Main Line Variations

After 1.e4 e5 2.Nf3 Nc6 3.Be2 Nf6 and now the energetic move that characterizes the Tayler proper, 4. d4!?, we reach a major crossroads:

Black must reply 4...ed to have any hope of equalizing.

If instead 4...Nxd4 5.NxN ed 6.Qxd4 and White is ahead in development with better central control. Similarly, if 4...Nxe4 5. d5 followed by 6. Nxe5 and White has the better game.

So continuing on after the more or less compulsory 4...ed after 5.e5!?, we reach the main position of the Tayler Variation:

In practical terms, with best play, I believe from this position that Black can achieve equality in some lines, but he must tread a careful path through some sharp complications first; not necessarily an easy task for even strong players as my game with IM Mike Valvo demonstrates in section A3. Certainly, although White is sacrificing a pawn in many lines, White has clear compensation in most cases and certainly does not incur any disadvantage out of the opening.

Here Black has three reasonable replies:

A: 5...Ne4

B: 5...Nd5

C: 5...Ng4

A: 5...Ne4

This is the variation that was the primary focus of attention back in the 80ʼs and was considered the

Tayler 3

main line. Blackʼs knight is well centralised but may experience difficulties on the e-file. Tayler gives 6 .0-0!? and from here, Black has played:

A1: 6...Be7 A2: 6...d6A3: 6...Bc5?!A4: 6...d5!

A1: 6...Be7

6...Be7 this is Rybkaʼs choice in the position but it doesnʼt seem to work out that well i.e. 7. Nxd4 Nxe5 8.Nf5 Bf6 (perhaps better is8...g6 with an edge for White) 9. Qd5! c6 (or 9...Nd6 10. Nxd6 cxd6 11. Qxd6 +/=) 10. Qxe4 d5 11. Nxg7+! Bxg7 12. Qb4 (diagram below) computers give this is as equal but White has better pawn structure, better development and a safer king to counter against Blackʼs better center.

A2: 6...d6

This was once thought to refute the opening due to lines like 7. Bb5 dxe5 8.Nxe5 Qd5! where Black is at least equal. Instead, White should play 8. Re1! f5 (now8...Qd5? is well met by 9. c4! with a clear advantage to White) 9. Nxe5 Qf6 10. Nxc6 bxc6 11. Bc4 (diagram) and White has clear

compensation.

A3: 6...Bc5?!This attempt by Black to hang on to his booty is popular OTB, but it causes Black big problems due to the lack of good escape squares for the knight on e4. i.e. 7. Bd3! d5 (7...f5?! isnʼt much better: 8. Bxe4 fxe4 9. Ng5 Nxe5 10. Nxe4 Bb6?? {...Qe7 is better but after 11. Bg5 Qf8 12. f4! White has good attacking chances} 11. Bg5! and Black is losing his queen) 8. exd5 Nxd6 9.Re1+ and here Black can play 9...Be6? 10.Ng5! Qd7 (the surprisingly common panic reaction, 10...0-0?? is bad due to 11.Bxh7 Kh8 12.Qh5 and Black is lost) 11. Nxe6 fxe6 12. Qh5+ and White picks up the bishop on c5 as in Kane- Krause ICC 1996. Or instead of the horrible 9...Be6 he can try 9...Ne7 10.Qe2 and now Kane- IM Mike Valvo 1996 continued 10...Nf5? (diagram)

Qe5?! 0-0?? (...Bd6!) 12. Qxc5 whereWhite was winning thanks to the double blunders. Instead of the inaccurate 11. Qe5? White could have won rather straightforwardly with 11. Bxf5! Bxf5 12. Qb5+ and White picks up a piece.

A4: 6...d5!

As is so often the case in double king pawn openings, when Black finds the right moment to play ...d5 he can equalize as he does here.

7. Nxd4 Bc5 8. Bb5

and we reach a position from the Two Knightʼs Defence/Scotch Gambit normally reached via 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Bc4 Nf6 5. e5 d5 6. Bb5 Ne4 7. Nxd4 Bc5 8. O-O This position is considered playable for both sides/ dynamically equal.

Summary of 5...Ne4:

Blackʼs path to equality is relatively narrow here and in general White gets good play in most lines with full compensation in the lines where he sacrifices a pawn. This line is seen fairly frequently- around 30%. Of the other major Black alternatives at move five, 5...Ng4 is the most popular with something like 60% of my games reaching that position. The subject of the next section, 5...Nd5 seems to be the least popular, with it showing up in only about 10% of my games.

B: 5...Nd5

This is the least popular response to 5. e5 even though it seems playable for Black. The normal move for White here is 6. 0-0!? though in internet blitz games I sometimes play 6. c3 here counting on the fact that many of my opponents will blindly

Tayler 5

play 6...dxc3?? which of course drops the knight on d5. 6. Nxd4 has also been tried: 6...Nxe5 7. 0-0 d6 8. Re1 Be7 9. Bb5 c6 (9...Kf8 and White can claim some compensation in the form of the displaced king though Iʼm not sure itʼs really worth a whole pawn) 10. Rxe5!? (the simpler 10.Nxc6 is possible here too) de 11.Nxc6!? bc 12. Bxc6+ Bd7 13.Bxe4 Rc8 and White has two pawns for the exchange. Whiteʼs queenside pawns look like a force to be reckoned with in the endgame thoughRybka seems to prefer Black here (-.48). Even so, I would rather play White.

From the last diagram, 6. 0-0!? is Taylerʼs move. Black has played three replies:

B1: 6...Be7

B2: 6...Bc5

B3: 6....d6

B1: 6...Be7

This move looks sensible enough but White seems to get the upper hand after 7. Nxd4 i.e 7...Nxe5?

8. Nf5! with a double attack on the d5 knight and the g7 pawn or 7...Nxd4? 8. Qxd4 Nb6 9. Qg4! g6 (9...0-0? 10.Bh6 and White wins material) 10. Bh6 d6 11.Qg3 dxe 12.Qxe5 and White has a clear, possibly winning advantage. Indeed, after7.Nxd4 Blackʼs best is probably 7...0-0 8.Nf5 Nb6 9. a4 a5 10. Be3 where White can obtain the two bishops but has a slight pull at best. This remains to be tested.

B2: 6...Bc5

7. c3 d6 (of course not 6...dc3?? 7.Qxd5) 8.cxd4 Bb6 9. Bg5 Nde7 10. Nc3 dxe5 11. Bxe7 (11. dxe5 Qxd1 12.Raxd1 seems playable also) Nxe7 12. dxe5 Qxd1 13. Rfxd1 0-0 14. Rac1 Be6 15. Na4 (diagram)

Tayler 6

White can now eliminate Blackʼs two bishops here. Note that Black is ill-advised to grab a pawn here: 15...Bxa2?! as White has 16. Nxb6 cxb6 17. Rc7! and White recovers the pawn plus gets his rook on the 7th rank- White must be better here.

B3: 6....d6

This looks natural with Black aiming to dissolve Whiteʼs annoying e5 pawn. Play can continue: 7. c3 (again exploiting the pin on the d-pawn) dxe5 8. cxd4 e4 9. Ne5 Nxe5 10. dxe5 c6 11. Qc2 Bf5 12. Nc3 Bc5 13. Nxe4 with a roughly balanced position.

Instead of Taylerʼs suggestion of 7.c3 White has also tried 7. exd6 Qxd6 (Bxd6 is a reasonable alternative) 8.Bb5 Nf6 9. Re1+ Be7 10. Qe2 where White has some compensation- but again, is it worth a full pawn?

Summary of 5...Nd5

It seems that White does well in these variations mainly due to the vulnerability of the d5 knight vis-a-vis the queen on d1. Still, Black can reach playable positions particularly in the B3 lines. Of course, since there have been so few games in this variation (only one is included in Mega Base

2008) there is a lot more to be developed here and undoubtedly improvements will be found for both sides. OTB, these lines have proved to be generally easy to play for White.

C: 5...Ng4

After 6. 0-0!? we reach the mainline position (diagram below) and the most popular variations encountered OTB. This is generally considered Blackʼs best try against the opening. Indeed, Benjamin and Schiller went so far to give 5...Ng4 an exclamation point in Unorthodox Openings but I think that assessment is somewhat optimistic. White does sacrifice a pawn in most lines but I believe the resultant play is worth it.

From this position, Black has played:

C1: 6...Bc5

C2: 6...Be7

C3: 6...d6

C4: 6...Ngxe5

C1: 6...Bc5

Tayler 7

Tayler here gives 7. Bg5 f6 8. exf6 gxf6 (8...Ngxf6 is also playable) 9. Bh4 0-0 10. c3! and “White is better” -Tayler. If Black plays 10...dxc3 11. Qd5+ Kh8 unfortunately White does not win a piece as 12. Qxc5? fails to 12...cxb2!. Instead, 12. Nxc3 offers White a small edge.

C2: 6...Be7

7. Nxd4 Ngxe5 8. f4 Ng6 9. f5 offers White some initiative. If instead 7... Nxd4 8. Qxd4 Bf6 9. Qf2 Ne7 10. Nc3 d5 11. g4!? leads to a double

edged position with chances for both sides. White, for the moment, has the initiative but will have to play energetically to maintain it. Basman likes this variation for White but I think Black can hold on with best play.

C3: 6...d6

Again, Black is logically trying to eliminate the irritant on e5 but this move seems a little inconsistent with the previous 5...Ng4:

6...d6 7. Nxd4 dxe5 8. Nxc6 Qxd1 9. Rxd1 bxc6 10. Bf3! Bd7 11. Rxd7! Kxd7 12. Bxg4+ and White is winning.

Or 6...d6 7. Nxd4 Ngxe5 8. f4 Ng6 9. Nxc6 bxc6 10. Qd4! (diagram)

Tayler 8

This nice centralizing move has a record of tempting errors from Black in this position. To wit, one ICC game continued 10...c5?? 11. Qe4+ and White picks up material regardless of Blackʼs reply i.e. 11...Be6 12.Bb5+ Ke7 13. f5! and Black is lost. Another game of mine featured 10... Qf6!? (as Black wants to play Be7 without losing his g-pawn) 11. Qe4+ Be7? 12. Qxc6+ -oh dear!

Naturally, Black should have played 11...Ne7 but in that case, although he avoids dropping material, he still has to solve a thorny development problem on his kingside and that seems to be worth the pawn investment by White.

C4: 6...Ngxe5

This appears to be the critical variation, (for the time being at least), and White must demonstrate compensation for the pawn if the opening is to be considered viable. Given the lack of available material on the Tayler and the fact that what little is available boils down to a few disparaging references in various books by Eric Schiller (see the bibliography section), it seems that the lack of popularity of the line may plausibly be traced to the previously mentioned game, Schiller-Martinovsky, Chicago 1986. Described by Schiller

as a “debacle”, that game persuaded him to abandon the opening. I hope the improvement for White in that game suggested in this next section helps to reverse that neglect.

From the above diagram, White plays 7. Nxe5 Nxe5 8. Qxd4 (diagram below) now Black has a problem along the a1-h8 diagonal. As Tayler notes, with the queen controlling that diagonal “Black has difficulty completing his development”

Black has played a few different moves here

C 41: 8...d6

C 42: 8...Ng6

C 43: 8...Nc6

C 44: 8...Qf6!?

C 41: 8...d6

This move underestimates the pin of the knight against Blackʼs g-pawn. Play can continue: 9. Nc3 Be7?! 10. f4 Nc6 11. Qxg7 Bf6 12. Qh6 and White has recovered the pawn while retaining attacking chances.

Tayler 9

Or White can play 9. f4 Nc6 10. Bb5 Qf6 11. Qe4+ Kd8 12. Bxc6 bxc6 13. Qxc6 Rb8 14. Nc3 and with Blackʼs king stuck in the center, White is obviously better. (diagram)

C 42: 8...Ng6

Another effort to untangle. Play can continue:9. Nc3 c6 10. Be3 d5 11. Rae1 f6 (whatelse?) 12. Bh5 Be7 13. Qd3 0-0!? 14. Bxg6 hxg6 15. Qxg6 (diagram) and White has chances on the king-side with the immediate threat of 16. Bh6 and the idea of advancing the h-pawn in the air.

If Black here tries 16...d4 then 17. Bxd4! is one good reply

C 43: 8...Nc6

9. Qc3! and again the pressure against g7 is annoying: “Black is in trouble”-Tayler. Black has played:

C 431: 9...d5

C 432: 9...Qf6

C 431:

9...d5 10. Bb5 Bd7?! (10...Qd6 is a better defense i.e. 11 Bf4! Qc5 12. Ba4 Be6 13. Bxg7 Rc8 14. Bf4 and Black has an isolated pawn and still hasnʼt solved how to develop his Black squared bishop.) 10.Bxc6 and now 10..bxc6 11.Re1+ Be6 12. Qxc6+ Ke7 and White is winning. Or another game continued 10..Bxc6 11. Re1+ and Black apparently preferred 11...Be7 12. Qxg7 Rf8 13. Bg5 with a winning game for White to the equally horrific 11...Kd7 12.Qh3 Kd6 13.Bf4+ Kc5 14. a4! (14. Qc3 is also winning) where Blackʼs king will not survive long.

C 432: 9...Qf6

Tayler 10

10 QxQ gxf6 11. Nc3 Kd8 (Nd5 is a threat) 12.Nd5 Bg7 13.Bd2! (with the threat of 14. Bc3)

From here (diagram), Black has played:

C 4321: 13...Ne5

C 4322: 13..f5

4321: 10...Ne5

14. Bc3 d6 15. f4 Ng6 16.Rad1 (the simple 16. Nxf6 is fine too) and White will recover the pawn with a clear advantage i.e. 16...Bf5 17. Rd2 Nf8 18. Bxf6 Bxf6 19. Nxf6 etc.

Note that 13...d6 14. Bc3 transposes.

C 4322: 13...f5 -attempting to move the target

14. Bg5+ f6 (of course not 14... Ke8? 15. Nxc7+ etc.) 15. Nxf6 (diagram next page) where Black has to deal with the threat of discovered check through some means other than 15...Bxf6 16. Bxf6+ where he loses the rook.

This brings us to the previously mentioned contentious variation from Schiller- Martinovsky, Chicago 1986:

C 44: 8...Qf6! (threatening 9...Nf3+ winning the queen):

Schiller feels that this move leaves White scrambling to justify his pawn sacrifice. That game continued, 9. Qe4(?!) Be7 10.Nc3 c6 11. f4 Ng6 12. f5 d5 13. Qa4 Bc5+ 14. Kh1 Ne7 15. g4 b5 16. Qf4 h5 17.g5 Qxf5 and the rest was a mop-up operation 0-1.

Tayler 11

I believe White went wrong with 9.Qe4, a move that cedes one of Whiteʼs trumps in the position, namely his pressure on the a1-h8 diagonal. Perhaps, Schiller was afraid to exchange queens. OTB experience however has shown that White has nothing to fear from a queen exhange as his activity and Blackʼs development problems give him a good game.

A better White attempt from this position was 9.Qc3 and even though this results in something of a tempo loss, White won a good game anyway in Stonehouse-Cade, 1993 (Corr.)

Searching around for other possibilities in this position, I stumbled on the interesting move 9.Be3!? (diagram) which in addition to developing another piece (and not losing a tempo) ensures that in the immediate event of a queen exchange, White can recapture with the bishop and maintain the pressure against g7.

Some lines from the diagram:

The attempt to develop the queen bishop via 9...b6? fails to 10.Qe4 which not only hits the rook but threatens 11.Bd4 with a nasty double pin.

9...Nc6 doesnʼt look that good after 10.Qxf6 gxf6 11. Nc3 Be7 (again, Nd5 is a threat) 12.Nd5 Bd8

13. Bh6 (13.Rae1 is also good) d6 14.Bg7 Rg8 15. Nxf6 Bxf6 16. Bxf6 and White is better.

9...Be7 is probably the most sensible move, but even here Black can get in trouble. Another game of mine continued 9...Be7 10. Nc3 Ng6? 11. Nd5! and White regains his pawn with a better position i.e. 11...Qxd4 12. Bxd4 with a double attack against g7 and c7.

After 9...Be7 10.Nc3 the attempt to prevent Nd5 by 10...c6 came to grief after 11. Ne4! Qf5 12. g4! c5 13. Nd6+ Bxd6 14.Qxd6 Qe6 15. Bxc5 and White is obviously better.

9...Be7 10. Nc3 0-0 attempting to get out of dodge 11.Nd5 Qd6 12.Rad1 Nc6 13. Qf4 Bd8 14. Qxd6 cxd6 15. Bf4 Re8 16. Rfe1 Ne5 17. Bf1 a6 18 Bg3 and here Black stumbled with 18...Ba5? now after 19. b4! the bishop had no satisfactory retreat i.e.19... Bd8 and now 20. f4 won material in Kane- Sargon V (1-0 in 43)

9...Be7 10. Nc3 Nc6 is probably Blackʼs best line: White has activity and better development for the pawn. I would assess the position as dynamically equal. Alas, no human games have been played from this position so computer analysis will have to do for now. Fortunately, the results are very encouraging: Rybka 3, Fritz 11 and Hiarcs 11.1 assess the position as at least equal or slightly better for White: +.39, +.45 and +.31 respectively. Engine match results favored White: Rybka 3 vs Rybka 3, 1-0; Fritz 11- Rybka 3, 1/2 / 1/2; Hiarcs vs Fritz 11, 1/2/1/2; Fritz- Hiarcs 1-0for a total of 2 wins for White, 2 draws and no losses. Note that the draws resulted from the higher rated programs playing Black. In a few of the games, the non-development of Blackʼs queen bishop was a factor- Black often took a long time to get that bishop and the queenʼs rook in the game. Meanwhile, Whiteʼs two bishops and knight were very active. I expect these considerations will be factors in human games too.

Tayler 12

Summary of 5...Ng4:

It seems that White is doing just fine in all the variations after 6.0-0!? including the variation that had previously stymied Schiller. If somehow 9. Be3 doesnʼt pan out in time, then 9. Qc3 looks to be a decent alternative.

Conclusions:

It appears that the Tayler is perfectly sound though Black can achieve a few equal positions, mostly in the 5...Ne4 variation, where he can transpose into a well known equal position from the Two Knights Defense. If this remains the case, it means that the Tayler is probably at least as good as the Scotch Gambit, an opening with a lot more mileage on it. The remaining lines offer White a combination of traps for the unwary, exciting attacks and the joy of the initiative in most lines. Another point in its favor is the fact that it introduces a system of play as early as move three in the venerable double king-pawn opening complex. This means a high percentage of your games will allow you to exercise your theoretical knowledge while your opponents will be on the back foot right from the beginning of the game. Finally, I should mention that a few correspondence games have used Taylerʼs line with generally excellent results for White. Of the ten games in the database, White scored 6 wins, 3 draws and only one loss.

There is no earthly reason why this opening is not played more, especially when you consider that arguably more unsound openings such as the Blackmar-Diemer and the Latvian enjoy a wide following. Itʼs sad to realize that this is the first work on the opening (that Iʼm aware of, at least) since Basman and Tayler thirty years ago!.

I hope this article encourages more players (and stronger players than me) to explore its mysteries and further develop the nascent theory. I encourage you to play the Tayler, and if you do so, please send me your games! TIA

Biographical Note

Unfortunately, John Tayler hasnʼt left much of a trace on the internet aside from his opening variation. What we do know is that he read mathematics until 1955 at the University College of Leicester, UK. He was already a strong player at school- around master strength- and he usually played top or second board with good results. After school, he worked for GEC/EE Whetstone and played for Braunstone Chess Club and the County for many years. Sadly, he died sometime in early 80ʼs as a young man- probably in his early to mid 40ʼs. He had a reputation as a strong county player and was described as “intense”. One fellow club mate said “Games with John were always very tense.” Hopefully, he would be proud to know that his opening innovation has become internationally recognized and is still a viable line after all these years.
